Inspect the AMS cutter & filament path

Inspect the AMS cutter blade and PTFE tubes. A dull cutter or grooved tube causes filament jams and wasted prints.

  • Torch

  1. Open the AMS hub

    Remove the cover near the PTFE outputs.

  2. Check the cutter blade

    Look for a clean V-shape. Burrs or rounded edges = time to replace the cutter assembly (cheap part).

  3. Check the PTFE for grooves

    Old PTFE develops grooves that snag filament. Replace if you see deep score marks.

    Pro tip
    Keep a spare PTFE tube and cutter in your spares drawer. Both are very cheap and avoid a 2-hour debugging session.
